Someone posted a link in response to you, but no money actually crosses borders.

I think the best way to explain it is an example.

My contact needs to get money to his family across the world. I happen to have a cousin that I love and trust who lives there and runs a gas station. My contact gives me 10k USD + a fee and then I call my cousin and tell him to give 10k to the contact's family member if they give the right password. At the end of the year, I meet up with my cousin and I bring him some gold or other goods depending on what our deficits are to each other.
